pyTivo not working with Tivo "Beta Software Release"?

I recently noticed that my Tivo updated to reflect a "Beta Software Release" on my Premiere -- and now pyTivo doesn't seem to work.

I can see my Tivo through the pyTivo web admin page -- and I've confirmed that Windows is broadcasting the shares without any errors -- but my Tivo unit is NOT displaying the shares on that end of the connection.

Any ideas?
